抄録

The objective of this study is to evaluate internal consistency of a pilot questionnaire derived from qualitative analysis based on Triandis theoretical framework and to highlight valuable items leading to design a final questionnaire that discriminate patient who intend to wear denture and those who do not. Materials and Methods : The cross-sectional survey was carried out with 43 edentulous patients who fulfilled the inclusion criteria and gave consent for participation. Pilot questionnaire was administered to the subjects and response was recorded for analysis. Items were analyzed by correlation matrix and internal consistency were assessed by Cronbach's alpha of four Triandis theoretical framework subscales ; intention, social factor, affect and perceived consequence. Results : Of 72 pilot questionnaire items, 11 items were discarded based on the analysis resulting 61 (10 intention, eight social factor, nine affect and 34 perceived consequence) remained as valuable items with respective value of Cronbach's alpha ranging from 0.75 to 0.91. Conclusion : A pilot questionnaire was developed as a preparatory step leading to design an advanced questionnaire in multi-center investigation. Further multi-center investigation is needed in the future to analyze construct and convergent validity of the questionnaire to measure patients' intention to accept the dentures.
